Moses ben Abraham of Pontoise

Moses ben Abraham of Pontoise (12th century) was a French tosafist.

Moses was a disciple of Jacob Tam. In Tam's Sefer haYashar, a number of problems of Talmudic interpretation are posed to him by Moses. They became a standard part of the tosafot.^[1] In one, it is learned that Moses' brother let a convert live in his house and later partnered with him in business.^[2] Later tosafists also cite Moses in their commentaries on the Torah.^[1][3] Samson of Sens cites his commentary on the Mishnah. In the 16th century, Hayim ben Bezalel claimed to have a copy of this work. Moses also wrote liturgical poems.^[3] One, only two-lines long, is preserved in the Azharot of Elijah ben Menahem HaZaken.^[1]
